Necrophia is the mineral present in trellanstone that has the power to control amorphia, and which responds to the will of a sentient being.

The mineral is crystalline in appearance and runs in veins through the trellanstone. It is unclear whether trellanstone has other components besides necrophia that are important for the control of amorphia.

Necrophia is critical to the function of the Orb, making it therefore the vital material that allows all sorcery (other than Elder Sorcery).

According to Morrolan, it is beyond rare; it "only appears as a gift from the gods."
